Quelques pistes, tape un glxinfo pour avoir des infos sur l'acceleration, regarde les messages d'erreur dans /var/log/Xorg.0.log, optimiser ton xorg.conf.
Est ce que tu as redémarré ?(pas seulement ctrl + alt +bckspace )
Rebonjour, donc comme je le disais plus haut, le driver nvidia est bien installé, j'ai rebooté le pc apres l'install et voila les infos pour le var/log/Xorg.conf
